I want to practice performance testing at home using some load testing tool like jmeter. Can anybody tell me some links of websites or applications on which I can practice performance testing by throwing load by load testing tool from home?
It is not a LEGAL way to conduct load/stress test on any live websites/web applications without the permission.
So, you can deploy your own sample application or download sample applications available online and deploy it in your local server like Apache HTTP server or Apache Tomcat etc.
From my knowledge, You can use WebTours sample application from HP LoadRunner as an application to put your load.
Download HP Load Runner community edition from here. free for 50 vusers for life time. You need to create an account in the website.
You can download the webtours application from the HP website (comes with Apache HTTP server, which acts as a Web server).
Setup WebTours as per the instructions here
Confirm the successful installation/configuration by accessing the application from the browser (similar to http://localhost:8080/WebTours). The app is about flight booking (though not in real time ;) ).
Now, you can use the WebTours application as an AUT (Application Under Test)
Either you can continue with Load Runner or download latest JMeter version (3.1 as of now)
JMeter tutorials:
Getting Started
Component Reference
Builiding a Test plan
For Load Runner, there is documentation available in the following link to start with:
http://lrhelp.saas.hpe.com/en/12.53/help/WebHelp/Content/WelcomeContent/c_Welcome.htm
There is community support available managed by HP.
Use the sample applications which ship with the tool
Take your choice of open source application, install them on servers you own, manage and control. Use these applications as targets.
You are welcome to use api.jmeter.ninja. I built it for that purpose. A more formal API declaration is on it''s way but you can start with
http://api.jmeter.ninja/example.html.
http://api.jmeter.ninja/objects.xml
http://api.jmeter.ninja/objects/${OBJECT}.XML
Where ${OBJECT} is taken from the objects.xml page.
Or swap xml for dot json for the same in Jason format.
Exercises/Tutorial is available at http://api.jmeter.ninja/jmeter.pdf
Currently I just use this service for my own training sessions. But I hope to make it more generally available in the near future. There a currently no automatic limits so please just use your common sense and don't run high at throughput for a sustained periods of time. Anything under a total 100k requests is no problem.
Only caveat is that service is provided on a best effort basis at this point. Any abusive/problematic users may be blocked without notice.

I want to load test the web application that we're working on? Can you name some automated load testing tool for a website developed on asp.net mvc3? I would like to develop it for concurrent 100 users, 200 users and so on. We want to test it with many users and test the load that creates on the application and server.
BTW, we're also running profiler at the same time to find the application bottlenecks so that we can find code that is slow that we can improve.
There are a number of different options; they vary in all kinds of exciting ways.
I use the open source Apache JMeter for this kind of testing - it's not hugely user friendly, but is very powerful once you get used to it, and the lack of licensing restrictions means you can use it in all sorts of configurations.
Some of our projects have glued JMeter into the continuous integration cycle, running performance tests on nightly builds. Some projects need to scale to huge numbers of users, and we use JMeter in the cloud (there are some service providers who can do this too).
it works nicely with Asp.Net MVC apps.
We are currently load testing our MVC application and the external company uses a product called LoadRunner.
However, depending on how intricate your testing is you could use the WebClient class as a base to run your own volume tests.
Web Performance Load Tester works very well with .NET apps. We test a lot of them (disclaimer: I work for Web Performance and am closely involved with the product).
We have integrated with Fiddler load testing tool called StresStimulus
I've got a PHP site up and running, and the db is mysql. before launching the site, I would like to test the traffic handling. Now am assuming that there are soe softwares that would simulate the traffic and log the processes running on my site. Any recommendation of software I should use? the traffic doesn't have to be real, but nonetheless, I would like to generate a high traffic to investigate the threshold of the site.
Appreciate the help
You can use Gatling https://github.com/excilys/gatling.
It's a stress tool written in Scala which aims at being more efficient and lighter than Jmeter.
Basically you record a scenario on your website and then run it 'n' times in parallel.
Here is the wiki for more infos https://github.com/excilys/gatling/wiki/Basic-Usage
You can use Jmeter:
It's free.
it's easy to Start with lot of documentation on its Website and on internet
it has a proxy feature to easily create test plan from browser navigation
It is easy to start up processes on other machines. It remote testing, can be done from GUI or console.
The scripts can be written in beanshell, java, or any jsr223 language ( groovy, Javascript, scala, jexl ...)
it has a lot of built- in samplers and thanks to its plugin architecture it's very Easy to add new ones or use any scripting engine to do what's missing
it has great user mailing list
it has very reactive support
it's now a top Level Apache
it can run thousands of users
professional solutions exist to run it from cloud

Performing a Stress Test on Web Application?
Best way to stress test a website
How do you test the performance of a website?
I have developped a HTTP web service which is queried by smartphone. I want to test the performances of all this service containing :
A java server (java 6, java + play framework)
A database (Mysql 5.1.41)
A Linux (ubuntu) server (kernell 2.6.32)
I have tried leading test campaigns using python scripts with many threads or sequential tests. But it's hard to have conclusions...
I want to be able to have the maximum number of request per second for my service, the average time for each request... complete dashboards displaying a lot of information
I can do many scripts to test that but I am shure that well-known softwares permits to conduct these tests. Ideally these softwares could also display information about where I loose time ...
Do you have hints ?
Thanks for your help
Some tools I've used for HTTP benchmarking
Apache Bench
Siege
JMeter
Of these, JMeter is probably best for the situation you describe. All of these display a lot of information, but won't explain where you lose time.
For that, I'd suggest a profiler such as JVisualVM (comes with the JDK) or YourKit. From a profile you can observe where you spend the most time and focus on optimizing that.
I want to benchmark a new server using historical HTTP-request data. I have a textfile that contains one day's worth of real historical requests to a production server. What is the best tool for sending that list of requests on the server I'm testing? The tool I use should be able to configure the following:
Number of threads making the requests
Number of requests/second sent
A list of request URLs to use when making the requests.
Apache Bench seems like a close fit. However, Bench does not seem to be able to take in a list of request URLs as a parameter. What would you recommend?
I have been using http_load to pretty good success.
http://acme.com/software/http_load/
Http_load is a Unix command line tool that allows you to specify the number of requests/second and the number of threads to use when running. It pulls urls from a text file that you specify in the command. The tool is very similar to Apache Bench, with the big difference being that http_load allows you to use a list of URLs to be used when making requests. Apache Bench makes request to a single URL only.
If all your requests are GET requests (no POST) then you can use the JMeter Access Log Sampler. Here are some straight forward step-by-step instructions on how to set it up. It will run through your requests either in order or using a number of concurrent threads and you can specify how many requests should run. Then you can use the other features of JMeter like reports to analyze the results.
I would reccomend Visual Studio Test Edition. It would be a relativley simple matter to create a coded webtest that loads your url's for testing.
This advice predicates a knowledge of C# or VB for coding and the ability to install and licence Visual Studio. Visual Studio does have a trial edition available so you can have a taste of what you are getting first.
Visual Studio does not require the target site to be running any particular hardware or software, but it does provide more information on the load of the server due to the use of Perfmon counters and any ASP.Net application will provide more detail on the running app.
The caveat to this is that I have not actually used any other web testing software.
what is the best tool (open or commercial) currently available, that lets me send customized requests to a web server and get back a response to check the performance?
i will be sending it a load of more than 20K per second, but i need to get numbers for each call made. also, the numbers might be in some microseconds or nanoseconds. How in this small measurement unit, can i work out a baseline and a benchmark?
If you're using Apache, Apache AB is a benchmarking to test how many requests your serve can serve per second and how well it handles load and concurrency. It's an open-source project - check it out here.
In addition, wikipedia has a nice list of benchmarking software for testing servers.
You can use the Web Application Stress Tool of Microsoft
The Microsoft WAS web stress tool is designed to realistically simulate multiple browsers requesting pages from a web site. You can use this tool to gather performance and stability information about your web application. This tool simulates a large number of requests with a relatively small number of client machines. The goal is to create an environment that is as close to production as possible so that you can find and eliminate problems in the web application prior to deployment.
You can find a list of Open Source software for performance (most of them are for web that send custom request to webserver).
Don't know if either of these have granularity better than milliseconds but check out JMeter (open source) and LoadRunner (Commercial). LoadRunner is not cheap but it allows you to span load generation across multiple machines with aggregated results.
